This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study compares two minimally invasive catheter-based procedures for treating slow heart rhythms caused by overactive nerve signals. One approach uses freezing (cryoablation with the Freezor™ Xtra catheter), while the other uses radiofrequency energy (with the TactiFlex™ SE catheter). Both aim to calm the parasympathetic nerve endings in the heart that are causing your symptoms.
Radiofrequency ablation is the standard treatment, but it may not work as well when fat tissue around the heart is thick. Freezing might work more consistently in these situations, but no one has directly compared the two methods in patients with your condition yet.

You will undergo one of the two ablation procedures at a single center in Russia, performed under sedation. The doctor will place catheters through your veins into your heart, create a 3D map of your heart tissue, identify the problematic nerve clusters, and then either freeze or use radiofrequency energy on those areas. The procedure is designed to reduce or stop your slow-heartbeat symptoms and will be followed by monitoring to assess whether the treatment worked and whether any complications occur.
